Turn on gas
pull on choke
twist throttle two times , DO NOT TOUCH THROTTLE AGAIN!!
put foot on kicker and push until you come up against compression
pull compression release and move kicker about an inch
release compression release and return kicker to top of stroke and give it a SERIOUS kick

Should fire right up

If hot(like after a stall)
DO NOT TOUCH THROTTLE
Pull hot start
follow same procedure as above

If warmed up... try the same procedure without the hot start, most of the time mine fires right up.

It sounds complicated, but once you are used to it, it is second nature and takes much less time to do than it does to explain how to do it. All the trouble is worth it because these bikes rip!

Best way to start an 01-02 426 READ CAREFULLY1)remove all plastics2)remove the head3)install a HOTCAMS 4)put everything back together5) 1 kick6)go rideenjoy it

On a serious note, the removal of the head is not only NOT required to do an auto decompression update, it is in fact impossible to replace the cam with the head off the engine, since the head connot be installed with the cam in place.

i BOUGHT an 01 426 2 weeks ago and have only gotten it started twice since then. I have been reading on here for days about all the different starting techniques and she still wont fire. I'm guessing the plug is fouled by now? Do you really have to take the gas tank off to change a plug? :crook:

Ya, that's common on the 426. I run either an Iridium plug or a NGK "E" series. They have less tendency to foul.

buy cr8ek plug way better than stock, kick over till on compression stroke and it shouldnt move any more if it has good 426 compression, decompression just a tiny bit past tdc, brink kickstart back to top and kick over with no decompresion and should fire up

Turn the gas on, kick the bike through with the compression release pulled 2-3 times. Let the kick return to the top and without the compression release pulled find TDC(the hard spot). Pull the compression release and push it one click past TDC(meaning down past the hard spot but only a little). Then let the kick start return to the top of its stroke and kick it HARD all the way down to the foot peg.

Don't play with the gas or anything while your trying to start it. Keep your hand on the master cylinder of the brake if your not sure you can kick it without twisting the throttle. If you already did, you'll need to pull the plug and replace it or wait till tomorrow.

follow this procedure, also on my yz426 if i hav trouble starting, hold dwn the de-comp leaver n kick it a few times. then repet the proceduer. i tend to find it helps to also ply with the hot start and cold start choke. jst dnt giv 2much gas, a blimp is more the enough otherwise u will be kicking for a long time. also get to knw ur bike, see what it likes n doesnt like.. and dnt give up.. lol

Dont get frustrated - Sooo many of us have had the same challenge - it can be done! Used to be that none of my friends wanted to ride it cause they couldnt start it. I finally installed the new cam after hearing about others here and now it kicks like a too-smoke!
